HL-103 Sodium ethylenediamine tetramethylphosphonate EDTMPS
Properties:
EDTMPSis ethyleine tetraonacea acid, low toxic or non -toxic, non -polluting. On thesurface of the steel, hydrophobic membrane can be formed. It has good chemicalstability. It has a good dirt resistance effect below 200 ° C. It is excellentwater quality. Stable chelating agent.

Usage:
Circularwater and boiler's corrosion resistant agent, cyanomy -free partial agent,printing and dyeing process softener, and electric plant circulating dirt-proof dirt and dirt can also be used for pipeline pre -membrane.
EDTMPSis used as a solid concentration for a solid agent less than 10mg/L, theconcentration concentration of the merger is more than 100mg/L alone, and theconcentration of composite use of the low molecular mass stuffing agent is lessthan 5mg/L. In terms of metal surface cleaning and processing, the effect of1%~ 5%EDTMPS is equivalent to dilute hydrochloric acid. EDTMPS and NA2MOO4composite matching can prevent the former former metal corrosion.
Packingand storage
25ibc or 200ibc plastic drum packaging, placed in a cool and dry place, valid for twoyears.
SafetyProtection:
EDTMPSis alkaline. When operating, pay attention to labor protection. You shouldavoid contact with the skin and eyes. After contact, you should immediatelyrinse with a lot of water.
